I have three bags that each contain 100 marbles: • Bag 1 has 75 red and 25 blue marbles; Bag 2 has 60 red and 40 blue marbles; • Bag 3 has 45 red and 55 blue marbles. I choose one of the bags at random and then pick a marble from the chosen bag, also at random. What is the probability that the chosen marble is red?
